My processor is an AMD A8 3870k, and have installed 4gig RAM, my GPU is a GT240 ddr5. Everything is smooth. However, I have heard that compared to an Intel processor, my procie is far behind, especially in the multitasking capabilities. My question is would adding another 4gig RAM improve my system's multitasking capacity? Or would I just be wasting my money on the additional RAM?
